The bracketcooperates with the pawl I in rier G, while thepawl H. the rack bar "J.These pawls are adaptthe pawl carrier and they are pressed outward bya'highly. T interposed between the carrier. rack bars as shown in Fig.4=,.but when the to receive a spring drum M carrying a tape N secured ata to the pawl carrler G. Any

suitable spring drum may be employed, but preferably the spring m iscarried wlth n the drum and the tape N is wound on'the periphery of thedrum. As shown in Figs. 7 and 9, the drum is supported on a shaft 0 towhich the spring is attached as indicated in Fig. 5. handle 0 and also aratchet wheel 0 engaged by a pawl or dog 0 By properly setting the pawl,the spring drum mechanism may be locked.

The lower end of the rack bar K is'provided-with an arm to which issecured a horizontally arranged rod P extending through a bracket 2)attached to the frame on the typewriter. The rod carries a key Q, whichI call thefline key as it is used to operate the mechanism for movingthe line indicator step by step from line to line on the copy.

Fig. 3 indicates how easily the key mechanism may be applied to atypewriter of orsecured to the frame ofthe typewriter and the rod P maybe extendedthrougha hole 7 on the typewriter frame.

A spring R, connected with the key Q. and witha fasteningdevice Sapplied'to a suitable part of the typewriter frame, serves to hold thekey in its normal orelevatedpd sition. The construction is such: thatwhen the key is depressed. the rackv bar 7 K is moved a short distancedownward and when the key is released itreturns'to normal position andthe rack bar. K is moved one, step backward or upward.

cooperates with ed to move horizontally in tempered spring pawls. Saidpawls are provided with pins andz" respectively. Each pin extendsthrough a wide opening in the pawl carrier so that the pawls may havesufficient freedom of movement and preferably the pins are detachablyconnected to the pawls to facilitate in assembling or removing the partsfrom the pawl Normally the pawls engage the line key is depressedtherack bar K is moved downward and as this bar engages the pawl I, thepawl carrier with the line indicator will be moved downward one space.At the sametime, the pawl H ismoved downward,

withdrawsfrom one tooth in the bar J, and

- engages another tooth below it. In this way the pawl carrier and lineindicator are moveddownward relatively to the copy and the teeth in therack bars and the operating mechanism aresuch that theline indicator barKreturns to its original position,

This shaft carries a winding" p may be.

The rack ,bar K the pawl caring with writer frame attached end of thespring tance between two lines on the copy. 7

As soon as the line key is released, the rack 2:. ;e., it moves upwardthe space of one llne and the pawl I engages another lower tooth in theseries, but while the rack bar K is thus moved upward onespace, the pawlcarrier G cloesnot move; It is held in its lower position by the pawl H.

It is, of course, not necessary that the bar K should be so moved thatthe pawl I will engage each'tooth in the series, as it is obvious thatin the normal operation it may and often does skip or pass over severalteeth. The amount of movement given to the pawl carrier is. governed bythe amount of movement given to the operating key.

The sprin drum connected to the pawl carrier places a tension on thepawl carrier so that the latter is held in enga 'ementwith therack bars.When the paw carrier is moved downward it does so against the force thespring. lVhen it is desired to move the ruler back to the top ofqthecopy .or to anyiother placethereon, the spring pawls H and I'may bewithdrawn by means ofthe headed pins it, i and then the ruler may bemoved freely to any desired place on the copy. By means of thepawl 0 thespring drum mechanism may be securely locked so that the devlce Wlll notoperate until re-': leased. u v

I claim as my invention 1. The combination with a typewriting machlne ofa copy holder, comprising-a copysupporting plate, allne indicatoradapted to move over said plate, a pawl carrier to which the lineindicator is connected, a pawl' mounted on the carrier,

the pawl in the carrier,1-an"opera'ting key mounted within thetypewriter frame, a shaft to which the key is secured,

a bracket attached. to the frame of the type-, 7

v'riting machine through whichthe shaft pa'sses,-a connectionbetweensaid shaft. and

a rack bar 'cooperat-"q the rack bar, andmeans for locking'the pawlcarrier and line indicator in set position.

2. The combination wlth a typewritmg machine of a copy holder,comprising a copysupporting plate, a line indicator adapted to move oversaid plate, a pawl carrier to which the line indicator is connected,pawls mounted on said carrier, rack bars cooperating withthe pawls, anoperating key mounted. within the typewriter frame, a bracket secured tothe frame of the'typewriter, a shaft extending through said bracket andtorwhich the key is attached, a spring within the typeto the, key formovingit in one direction, devices for attaching one to'a part of thetypewriter frame, 'a connection between one of the rack bars and saidshaft, and devices carried by the pawl carrier cooperating with oneofthe' rack bars for holding the pawl carrier and the line indicator inset position.

3. A copy holder, comprising a supporting plate, a line indicatoradapted to move over said plate, a pawl carrier to which the lineindicator is connected, pawls mounted on the carrier, rack barscooperating with the pawls, means for actuating one of said rack bars tomove the pawl carrier with the line indicator, means for locking thepawl carrier to the other rack bar, and means for exerting an upwardtension on the pawl carrier. 1 V

4. A copy holder, comprising a supporting plate, a line indicatoradapted to move over said plate. a pawl carrier to which the lineindicator is connected, pawls mounted on the carrier, a springdrumconnected with the pawl carrier and exerting an upward tension thereon,rack bars cooperating with the pawls in the carrier, means for actuatingone of said rack bars to move the pawl carrier with theline indicatoragainst thetension of the spring ClILHIl,-I11GZ1I1S cooperating with theother rack bar for holding the pawl carrier and line indicator in setposition, and a pawl for holding the spring drum in locked condition.

5.
